--- Comment #6 from emersion contact@emersion.fr --- Agreed that this is an IGT bug, not a driver bug.
Just sent an IGT patch that attempts to fix the issue.
User impact: the user might experience corrupted frames via HDMI. In other words: we don't check anymore that HDMI is properly working since this test is broken.
Other CRC/frame tests aren't run after a crash (this is the first one).
